Frozen butter is the trick to these light flakey buttery biscuits! To make cheese biscuits, add in 1-1/2 cups grated cheddar cheese to the flour mix before adding in the buttermilk. I separate into two balls, and refrigerate for 1 or more hours before cutting into biscuits, this give the gluten in the flour time to relax, and makes for a better biscuit. Although I have never tried this I'm quite sure the recipe may be cut in half, as there is quite a bit of dough to handle with the recipe, any leftover biscuits can be frozen. Don't forget frozen butter only, that's the trick to a light and airy biscuit!
